Replying to: minismom (Jul 15, 2008 6:47 am) It could be a defective 02 sensor, or the wiring/circuit to that sensor and worst possible case would be a defective PCM (brain) module.   This can all be tested by a competent diagnostician---no guessing required.

#148 of 185 I like my Deposits in the Bank by oldfarmer50 Jul 17, 2008 (7:27 am)
I have been hearing a lot lately about fuel system cleaners and injector flushes to clean out "deposits". I thought I understood all about this but I'm wondering now if I do.   So take me to school. Where do these deposits come from, do any of the dealer offered or over the counter products work and what exactly are they supose to cure?   Is this the modern equivalent to "blowing the carbon out" by racing up and down the highway?
#149 of 185 Fuel pump by jason46 Aug 31, 2008 (12:07 pm)
Please help. I have a 1992 Cherokee Jeep and it died on the highway. There appears to be no power going to the fuel pump. Any ideas on finding out where the power has broken down? Replies to this message: kiawah (Aug 31, 2008 8:06 pm)

#151 of 185 Where is the fuel filter? 2000 Chrysler concorde lxi 3.2 L by ashtrizz Sep 27, 2008 (8:24 am)
I am wondering where the fuel filter is for the 2000 chrysler concorde lxi 3.2 L? Also we are gonna change the fuel pump and want to know if you have to drop the gas tank or if you can get to it threw the trunk? Replies to this message: Mr_Shiftright (Sep 27, 2008 8:35 am)

Replying to: ashtrizz (Sep 27, 2008 8:24 am) A combination fuel filter and fuel pressure regulator is used on all gas powered engines. It is located on the top of the fuel pump module.   The fuel pump module is an in-tank unit with an integral fuel level sensor and pressure regulator.   Yes you have to remove the fuel tank.
#153 of 185 Ooops - gas cap off during car wash! by budh Dec 09, 2008 (11:19 pm)
I filled my tank yesterday evening in my 153,000 mile 2002 Highlander Limited AWD V6. Then went through an automatic car wash before driving five miles home. When I got out of the Highlander I saw the gas cap was off and was off during the car wash!   No issue with my five mile drive home.   What would you do to make sure it keeps running right after this error?   And now that I have reinstalled the gas cap properly, can I prevent the check engine light from coming on?   (I live in a fairly cold climate near the Indiana/Michigan state line.)   Bud H Replies to this message: jipster (Dec 10, 2008 7:56 am) Mr_Shiftright (Dec 10, 2008 11:27 am) bolivar (Dec 17, 2008 6:32 pm) Mr_Shiftright (Dec 17, 2008 7:05 pm)

Replying to: budh (Dec 09, 2008 11:19 pm) May pour a tank of STP gas cleaner into the tank. It's suppose to remove/isolate any water... though if more than a few ounces got in I doubt it would do any good. May have trouble with gas line freezing when it gets cold. Could siphon remaining gas out.

Replying to: budh (Dec 09, 2008 11:19 pm) Depends how much water got in there. It has settled to the bottom of the tank. I'd say you might either never go below 1/4 full if you can, or you can 'test' things out by deliberately going to 1/8th full or so and if the car starts to sputter, you might have to drain the gas tank to get rid of that much water.   If it's just a teeny bit of water, the engine will burn that up after gasping a few times.
